Are dental patients able to perceive erosive tooth wear on anterior teeth?: An internet-based survey assessing awareness and related action

BackgroundErosive tooth wear (ETW) is irreversible loss of dental hard tissue. The authors examined patients’ ability to recognize ETW relative to sound teeth and teeth with caries.MethodsUsing Amazon’s crowdsourcing service, the authors recruited participants (N = 623) to view standardized images of buccal surfaces of teeth (sound, ETW, or caries). Participants reported whether a dental condition existed (yes or no), likelihood to seek care, and esthetic attractiveness for teeth with no, initial, moderate, or severe signs of ETW or caries.ResultsDental patients showed poor recognition of cases of ETW, especially compared with sound and caries-affected teeth at each level of severity. Patients were less likely to schedule a dental appointment for care or treatment of teeth with ETW than for teeth with caries at each level of severity. Patients also found ETW more esthetically attractive than caries at each level of severity and found initial ETW more attractive than sound teeth.ConclusionsDental patients struggle to recognize ETW, in general and compared with caries, at each level of severity and particularly for early stages of ETW. These recognition difficulties likely arise, in part, from tooth esthetic attractiveness standards (smooth and shiny teeth look more esthetic), possibly leading to lack of appropriate care-seeking behavior.Practical ImplicationsThis internet-based tool may be used to assess dental patients’ awareness and ability to recognize cases of ETW. Improved patient awareness might lead to seeking professional care to prevent or delay ETW progression.

Associations of appetitive behaviors in 7-year-old children with their cardiometabolic health at 10 years of age

Background and AimsAtherosclerosis begins early in life, thus optimal cardiovascular health needs to be promoted early. We investigated whether appetitive behaviors among 7 year olds are associated with their cardiometabolic health years later.Methods and ResultsA sample of 2951 children from a Portuguese birth cohort was analyzed. The Children's Eating Behavior Questionnaire assessed eating behaviors, and a measure of cardiometabolic risk (higher risk group: those in the upper quartile of triglycerides, homeostatic model assessment-insulin resistance, waist circumference and systolic blood pressure and in the lower quartile of high-density lipoprotein cholesterol z-scores) was created. Linear and logistic regressions were run. Children with more food avoidant behaviors had lower cardiometabolic risk (Satiety Responsiveness – boys: OR = 0.39, 95% CI 0.16; 0.93, girls: OR=0.37, 95% CI 0.17; 0.82 and Slowness in eating – boys: OR = 0.49, 95% CI 0.25; 0.95, girls: OR = 0.49, 95% CI 0.27; 0.91). Food approach behaviors (Food responsiveness (CEBQ-FR), Enjoyment of food (CEBQ-EF) and Emotional overeating (CEBQ-EOE)) increased cardiometabolic risks (e.g. CEBQ-FR: boys: OR = 2.50, 95% CI 1.45; 4.32, girls: OR = 2.33, 95% CI 1.46; 3.71). CEBQ-EF had stronger effects in boys, while CEBQ-EOE was positively associated with cardiometabolic risk among girls. When adjusting for BMIz at 7y, associations did not remain significant. Appetitive behaviors were also associated with isolated cardiometabolic parameters; the strongest association being with waist circumference.ConclusionsAppetitive behaviors at 7-years are associated with cardiometabolic risk at age 10. While ‘food avoidant’ behaviors protect against cardiometabolic risk and ‘food approach’ behaviors increase cardiometabolic risk, these associations are largely dependent of child's adiposity.     

Effects of a synbiotic on symptoms,and daily functioning in attention deficit hyperactivity disorder – A double-blind randomized controlled trial

Some prebiotics and probiotics have been proposed to improve psychiatric symptoms in children with autism. However, few studies were placebo-controlled, and there is no study on persons with an attention deficit hyperactivity disorder (ADHD) diagnosis. Our aim was to study effects of Synbiotic 2000 on psychiatric symptoms and functioning in children and adults with ADHD without an autism diagnosis. Children and adults (n = 182) with an ADHD diagnosis completed the nine weeks randomized double-blind parallel placebo-controlled trial examining effects of Synbiotic 2000 on the primary endpoints ADHD symptoms, autism symptoms and daily functioning, and the secondary endpoint emotion regulation, measured using the questionnaires SNAP-IV, ASRS, WFIRS, SCQ, AQ and DERS-16. Levels at baseline of plasma C-reactive protein and soluble vascular cell adhesion molecule-1 (sVCAM-1), central to leukocyte-endothelial cell adhesion facilitating inflammatory responses in tissues, were measured using Meso Scale Discovery. Synbiotic 2000 and placebo improved ADHD symptoms equally well, and neither active treatment nor placebo had any statistically significant effect on functioning or sub-diagnostic autism symptoms. However, Synbiotic 2000, specifically, reduced sub-diagnostic autism symptoms in the domain restricted, repetitive and stereotyped behaviors in children, and improved emotion regulation in the domain of goal-directed behavior in adults. In children with elevated sVCAM-1 levels at baseline as well as in children without ADHD medication, Synbiotic 2000 reduced both the total score of autism symptoms, and the restricted, repetitive and stereotyped behaviors. In adults with elevated sVCAM-1 at baseline, Synbiotic 2000 significantly improved emotion regulation, both the total score and four of the five subdomains. To conclude, while no definite Synbiotic 2000-specific effect was detected, the analysis of those with elevated plasma sVCAM-1 levels proposed a reduction of autism symptoms in children and an improvement of emotion regulation in adults with ADHD.Trial registration number: ISRCTN57795429.     

Application of disaccharides alone and in combination,for the improvement of stability and particle properties of spray-freeze dried IgG

Purpose: Spray-freeze drying (SFD) is a recently applied method to develop pharmaceutical powders. This study aimed to analyze the competence of Trehalose, Mannitol, Lactose, and Sorbitol instability and aerosolization of Immunoglobulin G (IgG) via SFD.

Methods: Induced soluble aggregates were quantified at 0 and 3?months, and 45?°C using size-exclusion chromatography. Conformation and thermogravimetric assessments were done by Fourier transform infrared spectroscopy and differential scanning calorimetry. Laser light scattering was performed to determine the particle sizes. Aerodynamic features were characterized by twin stage impinger and scanning electron microscopy.

Results: Although sugars/polyols preferably stabilized IgG following the process, storage stabilization was achieved in Trehalose, Trehalose-Lactose, Lactose, and Trehalose-Mannitol-based powders with soluble aggregates <5%. The conformation of antibody was preserved with β sheet content from 66.28% to 76.37%. Particle sizes ranged from 5.23 to 8.12?µm. Mannitol exhibited the best aerodynamic behavior, fine particle fraction (FPF: 70%) but high degree of protein aggregation during storage.

Conclusions: SFD could favorably stabilize antibody using Trehalose and its combination with Lactose and Mannitol, and also, Lactose alone. Sorbitol disturbed IgG powder recovery. Incorporation of other types of excipient is required for efficient respiratory delivery of IgG molecules.     

PTSD’s risky behavior criterion: Associated risky and unhealthy behaviors and psychiatric correlates in a nationally representative sample

Criterion E2 (“reckless or self-destructive behavior”) was added to the DSM-5 posttraumatic stress disorder (PTSD) criteria to reflect the established association between PTSD and risky and unhealthy behaviors (RUBs); however, previous research has questioned its clinical significance. To determine whether criterion E2 adequately captures reckless/self-destructive behavior, we examined the prevalence and associations of RUBs (e.g., substance misuse, risky sexual behaviors) with criterion E2 endorsement. Further, we examined associations between criterion E2 and psychiatric conditions (e.g., depressive disorders, anxiety disorders) in a population-based sample of trauma-exposed adults. We analyzed data from the 2012–2013 National Epidemiologic Survey on Alcohol and Related Conditions (N = 36,309). The Alcohol Use Disorder and Associated Disabilities Interview Schedule-5 assessed lifetime DSM-5 psychiatric conditions and self-reported RUBs. Among trauma-exposed adults (n = 23,936), multiple logistic regressions examined criterion E2′s associations with RUBs and psychiatric conditions. After adjusting for covariates, all RUBs were associated with E2 endorsement (AOR range: 1.58–3.97; most prevalent RUB among those who endorsed E2: greater substance use than intended [57.0 %]) except binge eating, and E2 endorsement was associated with increased odds of PTSD, bipolar disorder, substance use disorders, and schizotypal, borderline, and antisocial personality disorders (AOR range: 1.65–2.75), and decreased odds of major depressive disorder (AOR = 0.76). Results support the clinical significance of criterion E2 through identifying associated RUBs and distinct correlates. These results may inform screening and intervention strategies for at-risk populations.
